tion, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to jointed and it consists in an, improved construction of the tip and sleeve forming'the coupling,

seas toeombinestrength,lightnesaandcheapness of manufacture.

Said improvement consists of a threaded tip attached to the tenon of one section of a rod, a shoulder on su'ch tip between the threaded end and the rod-section, a blank threadless space tween such shoulder hollow sleeve attached to the tenen of the other section of the rod, said sleeve havinga female thread to engage the threaded tip, said thread situated within the sleeve, the space between said thread and the end oi the sleeve enlarged below the th read to engage with the cylindrical portion of the tip, the end of sleeve abutting the shoulderot ihetip, which, in combination with the cylindrical surfaces and the threaded portions, will form a coinpact joint.

threaded My invention consists, further, in impart ing additional strength to the joint by abutting the Shoulder of the tip againsta shoulder provided in the sleeve at the junction oi'V the enlarged cylindrical mouth with the portion. l

My invention further consists in che: ien; ing thel ina-nner of constructing the tip sleeve to form the 'necessary shoulders and bearings-viz., a thin cylindrical metal shell having a threaded end, said shell placed on the tenon of the'wooden rod-section, a second shell mounted on the first or primary shell, one end of which shell will forni the shoulder and gun-rods; ysentis the-saine or cylindrical surface be-, and threaded end, and a l and ntion e of the tip.

reference is had to the accompanying drawings, forming a part of this specification, said drawings representing enlarged views.

Fig. 3 represents a view of a longer section than that shown in Fig.- l, being a full'view of the tip and broken sectional View of the jointed. Fig. 5 represents a view of a tip and a broken sectional view of the sleeve',V showing the manner in which the shoulder of the tip and shoulderof the sieo'veY ezigage. Fig. G represents the same jointed. 7o

Fig, 7 represents a sectional View of the tip and sleeve constructed of a series of shells. Fig. S represents a l'ull View of the tip shown in Fig. 7.

Its construction is as follows: A i3 repre- 75 sont the Wooden rod-section; C D, their respective tenons to receive the tip and sleeve. E is the tip, and l? the sleeve. 'lhc tip and sleeve are preferably made of thin metal tubing of sui'licient thickness to form the threads 8o and give the necessary strength to all the parts. The tips and sleeves of the couplings shown in Figs. 1, 2, I5, and 4 are substantially the san1e,tlie diiference consisting only in the length of the sections. rods the devices shown in Figs. l and 2 would undoubtedly be used.

In Figs. l and 3 thetip E is fastened tothe tenen C in the usual manner7 said tenen ex tending, preferably, through said tip, said tip 9c having the threaded end e, and shoulder l). The thread on the end ot' said tip docs not extend to said shoulder, but a smooth cylindri-V cal surface e is left between suchVV shoulder and the thread. lf-he sleeve F is with the tei'nalo thread l to engage the threaded. end d of the tip. The mouth e of said sleeve from the end j' to the end got the thread d is eiiiarged below such threaded portion and engages with the cylindrical porice Endfof said sleeve abuts Y het the tipand'tvhen thel against shoulder sleeve. Fig. 4 repre- 65 In a cheaper class of provided two sections are screwed together a firm cylindrical coupling is made, as shown in Figs. 2 and 4.

In Fig. 5 a slightly-different construction is shown. The thread a' is cut up to the shoulder b', and the cylindrical portion c is situated between shoulder b and the shoulder h of the wooden section A. The sleeve I1" is made, preferably, of heavier material than the sleeves of Figs. 1 and 3.Y This is necessary to form the shoulder iat the junction of the cylindrical mouth e' and th read d'. In joining the two sections-viz., the tip and sleevethe shoulder z' ot` this sleeve will engage or abut against the shoulder b' ot the tip. The cylindrical mouth e of the sleeve and cylindrical part c' ot the tip will also engage each other. The end f of the sleeve may, if necessary, also abut againstshoulder h of the rodsection A, thus making when joined together, as shown in Fig. (3, a coupling apparently without a joint.

In the device shown in Figs. 7 and 8 the tip is constructed of a series of thin tubes or shells overlying each other. The primary 4shelly is placed on the tenon of the wooden rod`section, similiar to the devices shown in the other views, one end abutting against shoulder h of said section,the other end 7c being threaded. The secondary shell loverlies shellj, but is shorter than such shell and is situated between shoulder h of the rod-section and the end ofthread 7c. It' required, a third shell m, shorter than shell l and overlying the saine, may be placed against shoulder h of the wooden rod-section.

The sleeve G is made of' thin metal tubing and placed on the tenon D of wooden rod-section B. As said sleeve would be too thin to form an internal or female thread, I prefer in this case to insert within the sleeve and at the proper distance from thc end 'n the tl1readed ring o and secure it within said sleeve by soldering or in any other suitable manner. In joining the sections together the threaded portions will engage, as in the other devices. The end n of sleeve G will engage or abut against the end p of the short shell m. The

shoulder q of the shell l will engage the 'shoul,

der or end rfof the threaded ringo of the sleeve. The cylindrical mouthsof the sleeve will also engage the Acylindrical surface ot' the shell l. The short shell m may, if required, be dispensed with, in which ease the end 11y of the sleeve may abut the shoulder 7i of the wooden rod-section by making said sleeve as much longer as the width of shell in. This device (shown in Figs. 7 and 8) it is thought might be made cheaper than those shown in the other views, the principle embodied bcing the same, the difference consisting only in its construction. It is quite evident that the principle of construction above described, land shown in the several views-viz., the engagement of the threaded portions of the tip and sleeve, su pplemented bythe abutment of the end" of the sleeveagainst a shoulder provided on the tip, together with the engagement of the long cylindrical surface of said tip and sleeve-will make-a lrm com pact joint, thoroughly braced at all points, and much stronger than if such joint depended on the engagement of the threads alone. v

The cylindricalsurf aces ofthe tip and sleeve engaging each other will preserve the alignment of theA sections while the threads are engaging, andthus prevent crossing ofthe same.

Sho-rteningthe threaded portionof the tip and sleeve, enabling the joint tobe'quiek'ly put together, is another advantage of the cylindrical surfaces of the two sections. I prefer to employ double threadson the sections to further facilitate the coupling of the same.

Having thus described my invention, what I claim as new, and desirey to secure by Letters Patent, is l I. A gun-rod joint consisting of the sleeve F and tip E, each mounted on the tenon of a wooden rod -section and each provided, as showmwith the threaded portions a and d and smoothcylindrical portionsc and e and are; ranged to engage each other, as shown, come bined with the shoulder b, placed back ot' the` smooth portion c of the tip to engage the end f of the sleeve and thus provide an additional support, and with the respective threaded and cylindrical portions-of' said sleeve and tip, as Shown. l

2. In a gun-rod joint, thecombination,with the sleeve l", mounted on the tenon of a wooden rodsection, as shown.' having internallythreaded portion d and smooth cylindrical portion e between said thread and end f of said sleeve, ot the tip E, made of sheet-metal tubing, havingthreaded end a., smooth cylindril` cal portion c back of such threaded end, and.

shoulder b back otsaid cylindrical portion c, so that the end f of the sleeve shall abut irnily against said shoulder and thereby supple` ment and strengthen the engagement of V the respective threaded and cylindrical portions of the sleeve and tip, as shown.

In testimony whereof I affix my signature in presence of two witnesses.
